Improvement in railroad-car ventilators



PATEN EDWIN H. WINOHELL, OF NEW YORK, N. Y.

IMPROVEMENT IN RAILROAD-CAR VENTiLATGRS.

Specification forming part of Letters Patent No. 119,809, (lated October10, 1371.

To all whom it may concern:

Be it known that I, EDWIN H. WINOHELL, of the city, county, and State ofNew York, have invented new and useful Improvements in Railroad- OarVentilators and Dust-Deectors, and that the following is a full andexact description ofthe same, reference being had to the vdrawingaccompanyin g and making' part of this my specification.

The nature of my invention consists, first, in a device and apparatus ofa novel construction, placed upon and in the roof of the car, by whichfresh air is introduced into the interior along the entire length of thecar-body by means of a reversible conical funnel or hood, anddistributed through adjustable registers or valves; and, secondly, in apeculiar construction of air-and-dustdeliectors or leaves on either sideofthe car-windows, and so constructed and arranged as to detlect outwardand away from the windows the currents of air and dust produced in therapid movement ofthe car, the deectors being' movable on their vert-icalaxes so as to present a Hat surface to the air and dust, and facing itscurrent in either direction of the car 5 and, also, so as when thedetlectors are not operating' to fold or close with their outer edges ata very obtuse angle between the windows ot' the car, the two parts of myinvention operating', when the windows of the car are open, to produce acurrent or currents ot' air outward through the windows, and thustogether preserve the air pure and fresh within the car, and, by theoutward current, to keep the exterior air and dust from entering in atthe windows.

Figure l of the drawing represents a side elevation of the car, and ofthe Ventilating apparatus on the roof, and the deectors between thewindows, the latter in position for deecting the air and dust. Fig. IIrepresents the Ventilating apparatus in the roof by a verticallongitudinal section through the central axis of the apparatus. Fig. IIIrepresents a side elevation of the carbody, and the Ventilatingapparatus, and of the deectors, the latter bein g in the positionrequired when not operating and the windows closed. Fig. IV is avertical or top view of window and delecting-leaves in position to actas detlectors. Fig'. Vis a vertical or top view of window and the leaveswhen not in operation as deflectors, but closed at an obtuse anglebetween the windows.

In all the gures similar letters represent similar parts.

The construction and operation of my improvements are as follows: Uponthe roof ot' the car l place a attened tube or chamber, A, Figs. l, Il,lll, which extends along the whole length ol" the body of the car. Uponthe under side et' the chamber A are circular openings, B, Fig'. ll,co1'- responding with similar openings in the roof, and formingair-passages into the car. These openings correspond in number with thenumbers o" rows of Aseats across the car. Each opening is provided witha valve or register, I), opened and shut by means ot' a stem, t',beneath the root' o1" the car, and within reach ofthe passengers. Uponthe chamber A is placed the hood or hollow cone C, having' a collar bywhich it is connected with and opens into the chamber A. "his collar isequally divided by a diaphragmplate, c, Fig. ll. The hood and collar aremade to turn upon bearings surrounding air-openin g correspon din g withthe collar in the chamber A, so that the hood may be reversed to facethe opposite end or' the car. Across the chamber A, directly under theAcollar of the hood, is a lixed dividing-plate, l), Fig. II, whichdivides the ch amber into two parts, and when the hood and collar areturned in the line of the carin either direction the dividing'- plate inthe collar and in the chamber A exactly correspond, so that the currentsoi' air which pass into the hood are divided and equally distributed tothe two parts ofthe chamber A. The hood is provided with a stem, d',projecting down into the car, so as to be turned in the desireddirecwhich is set a plate of glass to till it, are fixedupon each sideof the windows in a vertical position, and vibrate upon gudgeons workingin brackets afxed upon the side of the car at top and bottom, so thatthe inner edges of the frames are close to and extend the length ofthevertical sides of the windows. The breadth ofthe frames will vary fromthree and one-half to tive inches according to the size of the windows;about one-third the width of the window may be taken as the fair averagebreadth ofthe leaves. These leaves are operated and made to act asdeflectors or otherwise by a horizontal rod or plate, G, which isattached to the car by suitable bearings, within which it is made toslide the required space for moving the deilectors, by means of asuitable gearing, such as a rack or pinion, g g', Figs. I, Ill, a-ndwhich is to be under the control of the conductor and not of thepassengers. Each leaf or deiiector has a bracket or arm bent out fromits lower edge horizontally, having at its extremity a vertical pin,which passes into a suitable opening in the adju sting-plate Gr, and isthus hinged to it. The deilectors are so set and connected with theadjusting-plate Gr that, when a leaf or deliector is turned by the plateG so as to stand out at a right angle to the side Jface of the air, allthe other defiectors on all the wirdows on the corresponding sides willstand out at the saine angle, and the opposite leaves on the oppositesides of the windows will lie nearly flat to the face of the car, and beturned away from the direction in which the car is moving'. When thedeilectors are not in use for carrying off' and outward the air-currentsand dust, the conductor slides the plate G and fixes it in position.When the leaves stand with their outer edges together, their sidesforming together an obtuse angle between the windows, as shown in Fig. Vin top view in horizontal section, the position of the deiieetors whenoperating as such is shown in Fig. IV, in similar view and section. Thearin at the lower edge ofthe deflector, by'which it is hinged to theadjustingplate G, is seen in top view at l l in Figs. IV, V, and in endview or elevation at 1 l, Figs. I, III.

This operation of the above-described devices is as follows: The hoodbeing set with its openingl toward the direction in which the car ismoving, the air is, by the rapid motion of the train, iorciblyintroduced into the chamber A, and thence into the car, and regulated bythe valves and equally distributed by means of the dividing-plates inthe collar and across the air-chamber-A, as described. By setting thedeiiectors E as shown in Figs. I and IV7 the dellectors on that side oi'each window toward the direction oi' the movement of the car, standingstraight out from the face ofthe car, carry the currents of air and dustand cinders passing the line of the windows off and outwardly away fromthe Windows.

The windows may then be kept open without dust or air entering theWindow, the air making its exit from within o'utof the Window, andsupplied from the apparatus on the roof. The atmosphere within the caris thus kept pure and in circulation, and passengers may sit at the openwindows without being incommoded by the entrance of dust and cinders, orby too strong a current of air frolnwithout. When the deilectors are atthe position seen in Figs. III, IV, the windows being` closed, theeiiiect will be still in some slight degree to divert dust from theWindows, and, in cold Weather, prevent accumulations of snow and frostupon the closed windows of the car.

Having thus described lny invention and improvements and the operationof the same, what I claim therein as my invention, and for which Idesire Letters Patent, is

l. rIhe combination of a reversible hood or funnel, having adividing-plate, c1, in the movable collar, with the ilattenedair-chamber and the fixed dividing-plate D, constructed in the inanner,and operating for the purposes described.

2. The device and operation of sliding plate G on the side of a railroadcar, for the purpose of adjusting and holding in place deiiectOI-S E atthe sides of the window in the angles and positions and for the purposesshown.

3. rlhe deflectors or leaves E, constructed in manner and for thepurposes shown.

4.. The coinbination'of hood and air-chamber on the roof, constructedsubstantially as de scribed, with or without the dividing-plates@1 andD, with the deflectors at the windows, constructed and operatingsubstantially as described.
